Peer Identifier except Address does not work

  • I try to connect pfSense to an FreeSwan through IPSec Site2Site Tunnel, with an Dynamic IP. On my Site the IP is static, on the FreeSwan Site its dynamic. The IP is being resolved by Dyndns.

    On other Tunnels with static IP on the Remote Site I changed peers_identifier to address REMOTE-IP. Peer identifier = Peer IP Address in GUI to make the Tunnels work.

    I search a lot through Google, pfsense Forum and pfsense Redmime without success.

    It seems to me that Tunnels with other Peer Identifier than IP Addresses are not possible with pfSense.

    Has anyone similar an experience?

  • It works just fine if you use the dyndns hostname as the DN. EG-
    I've done remote IPsec clients using FQDN, but I haven't tried site to site, easier to use DN.

  • You mean Distinguished Name on Tunnels Tab, which resolves to
    peers_identifier fqdn ""?

    This was my first Intention, which did not work. After that I tried several Settings suggested in the Forums like NAT Traversal on/off, DPD on/off.

  • I mean set the remote host to the DNS record of the host, eg-, and use Distiguished Name as the peer identifier, putting the DNS name in the box ( On the dynamic side, use DN as the peer id, again using the DNS name (
    Works fine for me with pfSense on both sides. YMMV

  • Double, Tripple and more Times checked. Another try this morning with DN, but always

    ERROR: couldn't find the pskey for
    ERROR: failed to process ph1 packet (side: 0, status: 6).

    Luckily this is the only Site2Site with Dynamic IP on the Remote Site. I changed all other Tunnels to
    Peer identifier = Peer IP address
    to make them work.

    Has anyone successfully established a Connection between PfSense 2.0.2 and Linux Openswan U2.6.21/K2.6.30.10-105.2.23.fc11.i586 (Fedora 11) or an LANCOM Box with an Peer identifier other than Peer IP address?
